Confused on my cycle. Need help!

Okay ladies. I need some help figuring out my cycle. I had the Marina IUD and had a light period February 14-18th. Basically just spotting on and off durning those days. I had the IUD removed on 2/26 then had heavy bleeding on 2/28, 3/1, and then light bleeding from 3/2-3/3. So in total from 2/28 to 3/3. That would be considered withdrawal bleeding, correct? We are TTC and I'm not sure when to expect my next period, when I would be ovulating, when to test, etc. Thanks!
